SAX api :problems

[wxdqz]

HiI am using SAX approach for XML parsing and using Sun's api.I am facing an abrupt behaviour.For eg if I define an instance variable TEST (String),assign a value "test"and in doGet method i assign a value "tested".when i run the program(via web doGet is called) and it goes to any of SAXapi like startDocument or characters and i see the value of TEST it is "test"means whatever i assign in doGet it gets lost.I am not able to figure out the problem , please help me.regardsprateek
